Greater Athletic Training Yeilds Lower Pulse Rate After Stre
GREATER ATHLETIC TRAINING YEILDS LOWER PULSE RATE AFTER STRENUOUS ACTIVITY This experiment was performed to investigate the hypothesis: greater athletic training yields a lower pulse rate after strenuous activity. After performing Experiments 15.1 and 15.2 (Dickey 1995), our team decided to measure the increase in heart rate from resting to active between members of the same sex but with different athletic training experience. Our team was interested in investigated whether athletic training has an effect on pulse rate after strenuous activity. Athletic ability is subjective, therefore after evaluation, our team decided upon one common variable that could be measured in this type of experiment. The three subjects were asked to provide an average of miles ran during one week of cardiovascular training. To measure pulse rate, we used the standard method of holding the index and middle fingers to the carotid artery in the neck for 15 seconds. Multiplying this number by 4 gives the pulse rate per minute. Our prediction was that the higher the athletic training, the lower the resting pulse rate and pulse rate after strenuous activity. Before beginning the physical aspect of out expe
The control was subject number 1 with no athletic training. Second, there are numerous other independent variables that may have affected the pulse rates of the subjects. "Physical Inactivity and Coronary Artery Disease. Redwood City, CA: The Benjamin/Cummings Publishing Company, 1995. Subject 1, who had no athletic training, showed the highest resting and active pulse rates. riment, we took the resting pulse rates of all three subjects as a basis for comparison after the subjects performed the cardiovascular exercise. Several weaknesses were found in the experiment. The subjects were then asked the level of cardiovascular training in miles per week on average. A person with greater athletic training over a person with lesser athletic training has made the heart stronger through conditioning, which allows the heart to work less hard to pump oxygenated blood through the body. Our dependant variable was the pulse rate of the subjects, while the independent variable was the amount of athletic training the subjects had. The correlation of active and resting pulse rates among the subjects is shown in Figure 1.
